docs(linter): Add configuration option docs for eslint/no-misleading-character-class rule. (#15058)

These docs already existed, but weren't using the standard format.

Part of #14743.

Generated docs:

```md
## Configuration

This rule accepts a configuration object with the following properties:

### allowEscape

type: `boolean`

default: `false`

When set to `true`, the rule allows any grouping of code points
inside a character class as long as they are written using escape sequences.

Examples of **incorrect** code for this rule with `{ "allowEscape": true }`:
```javascript
/[\uD83D]/; // backslash can be omitted
new RegExp("[\ud83d" + "\udc4d]");
```

Examples of **correct** code for this rule with `{ "allowEscape": true }`:
```javascript
/[\ud83d\udc4d]/;
/[\u00B7\u0300-\u036F]/u;
/[👨\u200d👩]/u;
new RegExp("[\x41\u0301]");
new RegExp(`[\u{1F1EF}\u{1F1F5}]`, "u");
new RegExp("[\\u{1F1EF}\\u{1F1F5}]", "u");
```
```
